Review on Gorilla Waterproof Patch & Seal Liquid - Black 16Oz - Ultimate Solution For Quick Fixes (Pack Of 1) by Alexis Guiney

Rather than buy cedar boards to make some additional shelves for my catio I decided to use up some leftover plywood that was sitting around. Since plywood delaminates pretty quickly in rain I thought I'd try sealing the boards up with this Gorilla rubberized sealant. My past experience using Varathane has been futile, even with three thick coats water got into plywood and delaminated, coated surfaces also peeled up. Time for something better.I wanted to lather it on nice and thick so the liquid can made more sense than the spray. Be sure to use it quickly once the container is open as the thick goo starts to dry and clump when exposed to air. I thoroughly coated one side of the shelves so it looked smooth and glossy. Waited a couple of days and flipped them over and coated the other sides and edges. Gorilla rubber sealant dries pretty quickly, I'd say about 24 hours. It dries smooth and glossy, but is super sticky and tacky to touch. Debris and dust will stick to it, but you can rinse it off or paint over it to give it a non sticky surface. I sprayed some leftover Verathane over it to make it smooth, only time and weather will tell whether the Verathane layer peels up or not. I used waterproof adhesive to cover one side of the shelves with carpet for my cats, it will also hide any peeling should that happen. I'll update this review if water gets through the Gorilla coating and things start delaminating. Fingers crossed!PROS: Very little scent or odor, applies thick, dries clear and quickly, appears to tightly seal wood if coated on all sides, can work as an adhesive while still wet.CONS: Tacky and sticky when dry, attracts dust and dirt to stick to surfaces, inside of container starts to dry and clump if exposed to air for very long, can get some clumping when brushing onto smooth surfaces.
